BUTTON.

Application led September `1l, 1922. Serial No. 587,309.

To all whom t may concer/n.:

Be it known that l, FREDERICK N. Ross, citizen of the United States, residino at Detroit, in the county of lVayne and @tate of 5 Michigan, have invented certain new and useful improvements in Buttons, of which the following is a specification,

This invention relates to buttons and'has for its object an improved button of the typeV that is ordinarily used on over-allsand similar garments.

@ne of the common forms of buttons of this character is the so-called tack button; that is a button which is formed by a pair of V members that are secured to opposite sides of the fabric. One of the buttons is provided with an anvil and the otherwith a tack point. The tack point is driven through the fabric and turned over n the anvil in the other button part. This locks the two button parts together and to the fabric. However, these parts very easily tear out as ordinarily the fabric is only held by the tack shank.

Another very common button used, which is somewhat an improvement on this is thev This simply has two prongs in-v staple type. stead of one; these are clenched under a bar carried by theanvil button part. Y

The type of button that I have 4designed is an improvement on. buttons of this character; it not only has a plurality of prongs, but these prongs cooperate Vwith-the peculiar shape of both the anvil member and` the prong carrying member so that the fabric is, pinched around a complete ring thereby taking the strain off the prongs and making it practically impossible to tear the fabric from the button by enlarging the holes through which the prongs protrude. Furthermore, the prongs of the button are so designed in connection with the anvil, that the prongs all turn in one direction and twist about their own axes in encountering the anvil; This securely locks them to the anvil member and allows the prong part to be drawn clear down and clinched upon the fabric.

In the drawings:

Figure l is a cross section of the button attached to the fabric taken on the line of 1-1 of Fig. ,2. f V Figure 2 shows the button attached to a fabric. n

Figure 3 is an elevation of the prong part of the button.

such as shown in Fig. 4.

taken on the line 4 4 ofFigurel.

The prong part of the button is simply av stamping madevof a single piece` of metal formed into va ring a of half circular cross section or what i term beaded, and preferably three prongs protrude axially from thev inside of the ring and are Vbevelled as at c on only one sidewall the prongs being bevelled onthe same side.

Figure 4l is a section v Theanvil part of the button comprises a shallow cup` l which has. its edges turned over the .shell c. The main body of this shell is a cylinder having its edge turned over to forni the bead and having the other edge turned out into a flaring collar g to be engagedV by the turned over edges of the shallow cup portion d. The flaring position and the cup portion engage over the enlarged base it of the anvil. The head of the anvil is convexe-concave; that'is, the outside of the head has a concave annular groove, and at the center the'h'ead is formed into a convex hump. This convex-concave construction has important functional relations with respect to the turned-in bead of the shell and the prongs on the other partA of the vbutton as will presently appear. l

The fabric is designated y'. it will be seen that the turned-in bead of the shell is spaced from the annular groove in the anvil and is also of less width than the groove leaving an opening 7; of substantially circular cross sec'- tion, forming an annular prong socket. The

Vbutton parts are' automatically clinched togiven a sharp blow, the prongs willpenter Y the angular socket, the bevelled point will cause them to bend all in one direction,.and will also cause them to curl up in helices this fashion, ample room is'given the prongs to enter clear in up to their bases. This brings the inside of the beaded ring a, tightly v down onV the fabric Vand on the inside fof Curling up in Ythe beadoiil the shell. The consequence is that the goods is`V looked all around on the inside of the two inter-engaging beads and also.v on theA outside of the hump m of the anvil. The consequence is that the strain (is taken oil' from the prongs and transferred to the two engaging beads and the hump, consequently, the goods will not tear nearly as easily as if thestrain were on one or more prongs and the cloth around the holes throughwhich they protrude in the fabric. Not only is this a cheap and easy. button to manufacture,.but the assembled button eiiicaciously grips the fabricv and takes theV Vwith one or more prongs beveled on one sideV at their free ends,the anvil'and the shell so arranged with respect to the prong or prongs when the same are driven against the anvil they are caused to twist upon their own axes in helices into the socket afforded in the anvil member.

2. In a button, vthe combination. ot' an anvil part provided with a shell and an4 anvil and a prong part formed into a ring having one or more prongs,` which may be driven into and clinched in the anvil part.

3. In a button, the combination ot an anvil part provided with a shell and anvil torming a prong socket, `and a prong part coinprising a ring member having a pair of Yprongs projecting axially from the inside of the ring member and arranged to be driven into the prong socket of the anvil part and clinched therein,

4., ln a button, the combination of an anvil part provided with an anvil and a shell arranged to afford an annular prong socket,

projecting prongs from the inside of theA ring which can be driven into the annular prong socket et the anvil part and clinched y therein. i l

6. In a button, the combination of an anvil part comprising an anvil having a headk with an angular concave groove and a center hump and provided with a shell having 'aV turned-in bead engaging over-the anvil groove but leaving an opening into the groove, and a prong part comprising a ring having projecting from its inside axially directed prongs bevelled on one side, where-v by when the prongs are d iven through the opening and into the annular prong socket of the anvil they will be caused rto twist into helices.

7. ln a button, the coii'ibination ot `an anvil part con'iprising an anvil having a head formed with an annular concave groovey and a hump7 and a shell having its end turned over into a. beady overlianging the said annular groove but of less width than the same to provide an opening into the annular prong socket, and a prong part comprising a bead, like ring having projecting from its inside a plurality oi: axially directed prongs bevelled. on one side atl their Yfree endswhereby when they are driven against the anvil they are caused to twist into helices in the prong socket of the anvil part. ln testimony whereoic l afiix my signature.
